Abstract

An animal restraint and control harness (10) for use in conjunction with a leash (11) has a cord portion (15), a plurality of adjustment slides (16), a control slide (18), and a leash attachment eyelet (19). The cord portion (15) is threaded through the adjustment slides (16) and the control slide (18), as well as through the leash attachment eyelet (19), to form a plurality of loop portions (36) and a plurality of bridge portions (38). A first loop portion (36a) is adapted to fit around the neck of an animal, and a second loop portion (36b) is adapted to be fitted around the chest of an animal. A third loop portion (36c) is connected to the leash (11) by the leash attachment eyelet (19) and communicates with the second loop portion (36b) by way of the control slide (18) such that when the animal strains against the leash (11), the cord (15) is slidably translated in the control slide (18) so as to increase the size of the third loop portion (36c) and to decrease the size of the second loop portion (36b). The second loop portion (36b) cinches around the animal's chest, causing the animal to cease the straining behavior to relieve the cinching discomfort.

Description

TECHNICAL FIELD

This invention relates to animal harnesses, for example, of the type used for domestic pets in conjunction with a leash. More particularly, this invention relates to a girth tightening harness which, when a strain is brought upon the leash due to pulling by the animal, tightens around the animal's girth, causing the animal to cease the pulling behavior to relieve the tightness.

BACKGROUND ART

For many years, it has been known to use harnesses on domestic pets, such as cats or dogs, for the purpose of restraining or controlling the animal. Such harnesses include simple neck collars, and also more elaborate body harnesses which are typically fitted around the animal's chest as well as around the neck.

More recently, it has been known to use harnesses and collars which function in response to undesirable behavior by the animal so as to discourage such behavior. For example, one such undesirable behavior is that of pulling or tugging by the animal, when the animal is restrained on a leash. Many dog owners find such behavior to be particularly problematic when walking dogs, especially of larger breeds. Attempts to discourage such behavior have included simple choke collars which tighten around the animal's neck when the animal strains against the leash. Other, more recent attempts have included the use of harnesses which tighten under the foreleg pits of the animal when the animal initiates a strain on the leash or tie out. Examples of such harnesses are found in U.S. Pat. Nos. 4,964,369; 5,329,885; 5,359,964; and 5,370,083, all to Sporn, as well as U.S. Pat. No. 5,325,819 to Krauss which disclose harnesses which, when the animal strains against the leash, tighten upwardly and rearwardly under the animal's forelegs. U.S. Pat. No. 5,335,627 to Bandimere discloses a harness which tightens under the animal's foreleg pits by pulling upwardly when the animal strains against the leash. While these designs have proven effective in accomplishing the objective of discouraging pulling or tugging, it has been recognized that the cinching of the harness under the foreleg pits is often painful to the animal. Although a level of discomfort must necessarily be present when the animal strains against the leash in order to have the desired effect, it is believed that the effect can be accomplished while providing a higher level of comfort for the animal.

DISCLOSURE OF THE INVENTION

It is thus a primary object of the present invention to provide a harness for restraining an animal in conjunction with a leash.

It is another object of the present invention to provide a harness, as above, which is effective to discourage pulling or tugging by the animal.

It is a further object of the present invention to provide a harness, as above, which provides a higher level of comfort for the animal than previously known devices.

It is yet another object of the present invention to provide a harness, as above, which is adjustable and easily fitted on the animal.

It is a still further object of the present invention to provide a harness, as above, which is easy and inexpensive to manufacture using known manufacturing techniques.

These and other objects of the present invention, which will become apparent from the description to follow, are accomplished by the improvements hereinafter described and claimed.

In general, an animal restraint and control device includes a harness member adapted to fit on the body of an animal and to connect to a leash for restraining the animal. Means for cinching the harness around the animal's body, when the animal strains against the leash, is also provided so that the cinching of the harness stimulates the animal to responsively cease straining against the leash in order to relieve the discomfort caused by the cinching.

More specifically, the harness member is formed into a plurality of loop portions and a plurality of bridge portions. A plurality of adjustment slides engage the harness member, as does a control slide and a leash attachment member. A first loop portion is defined between the first adjustment slide and the second adjustment slide and is adapted to be fitted around the neck of the animal. A second loop portion is defined between the third adjustment slide and the control slide and is adapted to be fitted around the chest of an animal. A first bridge portion is defined between the first adjustment slide and the control slide, while a second bridge portion is defined between the second adjustment slide and the third adjustment slide. First and second sleeve members are provided to surround the first and second bridge portions, respectively, to prevent the formation of loops therein. The first loop portion is in slidable communication with the control slide so that when the leash is strained against, the harness member slides through the control slide so as to tighten the second loop portion around the animal's chest.

A preferred exemplary device incorporating the concepts of the present invention is shown by way of example in the accompanying drawings without attempting to show all the various forms and modifications in which the invention might be embodied, the invention being measured by the appended claims and not by the details of the specification.

PREFERRED EMBODIMENT FOR CARRYING OUT THE INVENTION

An animal harness, generally indicated by thenumeral 10 in the drawings, is designed for use in conjunction with a leash 11. The leash 11 includes asnap 12 which is affixed to alead 14.

Harness 10 generally includes acord portion 15, a plurality of adjustment slides 16, acontrol slide 18, and aleash attachment eyelet 19. Thecord portion 15 of theharness 10 may be a continuous length of cord or rope or may be in the form of a strap. Similarly, the cord, rope or strap may be fabricated from any number of appropriate materials, such as a braid material or flat woven Nylon.

The adjustment slides 16 are preferably made of a thin, flat, cast metal or other appropriate material. Each adjustment slide 16 is of a generally tapered shape defined by opposedtapered edges 20 which taper from afirst edge 22 to a substantially longersecond edge 23. As shown, each adjustment slide 16 includes a plurality ofapertures 24 therein.Apertures 24 are oriented in spaced relationship with one another, such that a first pair ofapertures 24a and 24b are located proximal to thesecond edge 23 of slides 16. Similarly, a second pair ofapertures 24c and 24d are located proximal to thefirst edge 22 of slides 16. For reasons which will become apparent as the description continues,apertures 24a and 24b are angularly offset fromapertures 24c and 24d at an angle approximating that of thetapered edges 20 of the slides 16.

Thecontrol slide 18 is similar to the adjustment slides 16 in that it can be made of the same material and is of approximately the same thickness, although it is preferably slightly longer. Further,control slide 18 includes three pairs of angularlyoffset apertures 26. A first pair ofapertures 26a and 26b are angularly offset from a second pair ofapertures 26c and 26d proximal to afirst edge 30 at an angle approximating that of thetapered edges 28.Control slide 18 differs from adjustment slides 16 in that theapertures 26a and 26b are approximately 1/3 larger in diameter than theapertures 26c and 26d. An additional pair ofapertures 26e and 26f are located adjacent to theapertures 26c and 26d, proximal to thesecond edge 27.

Leash attachment eyelet 19 is also preferably made from a material similar to that used for theslides 16 and 18. In the preferred embodiment,eyelet 19 includes aharness ring portion 31 and aleash ring portion 32. As shown,harness ring portion 31 is disposed generally perpendicularly to leashring portion 32. Those skilled in the art will recognize thateyelet 19 could take many different shapes or designs and still accomplish the objects of the invention. For example, it is contemplated that theleash attachment eyelet 19 could be in the form of a single ring or a swivel.

Theharness 10 may be assembled with thefirst end 34 ofcord portion 15 being threaded through aperture 26c ofcontrol slide 18.End 34 ofcord 15 is then secured to controlslide 18 by melting, stitching or knottingend 34 so that it may not pass back through aperture 26c. The second end 35 ofcord 15 is then threaded throughaperture 26e directly adjacent to aperture 26c in the manner shown.Cord 15 is then similarly threaded throughapertures 24b and 24d of each of adjustment slides 16. Oncecord 15 has been threaded throughapertures 24b and 24d of each of the adjustment slides 16,cord 15 is then passed through aperture 26a ofcontrol slide 18, through theharness ring portion 31 ofeyelet 19, and back through thecontrol slide 18 at theaperture 26b.Cord 15 is then threaded back through the remainingapertures 24a and 24c of each of the adjustment slides 16. The second end 35 ofcord 15 is finally threaded throughapertures 26d and 26f, which remain in thecontrol slide 18, and secured thereto in a manner similar to that used forfirst end 34. Those having skill in the art will recognize that for efficiency and simplicity the harness may be assembled in numerous different ways and that the assembly steps set forth hereinabove are used merely for clarity of description. for example, it may be preferred to insert thecord 15 into theattachment eyelet 19 and thread both ends 34 and 35 through the slide apertures simultaneously. Accordingly, thecord 15 cooperates with theslides 16 and 18 to form asymmetrical harness member 10.

Withcord 15 threaded and secured toslides 16 and 18,harness 10 defines a plurality ofloop portions 36 and a plurality ofbridge portions 38. Specifically, afirst loop portion 36a is defined by the portion ofcord 15 located between the adjustment slides 16a and 16b. Similarly, asecond loop portion 36b is defined by the portions ofcord 15 located between adjustment slide 16c andcontrol slide 18. A third loop portion 36c is defined by the cord portion extending from control slide 18 toattachment eyelet 19. Afirst bridge portion 38a is defined by the portions of thecord 15 located betweencontrol slide 18 andadjustment slide 16a, and serves to connect thefirst loop portion 36a with thesecond loop portion 36b. Likewise, asecond bridge portion 38b is defined by the portions of thecord 15 located between adjustment slides 16b and 16c, thus further serving to connectfirst loop portion 36a withsecond loop portion 36b.

It is contemplated that the portions of thecord 15 formingbridge portions 38 may be secured together so as to maintain thecord 15 in a substantially closed state, thereby preventing the formation of a loop in the vicinity ofbridge portions 38. Accordingly, sleeves 39, preferably formed from a length of tubular material, such as braided Nylon or vinyl, may be fitted overcord 15 during the assembly process. Alternatively, the cords may be fastened together using a clasp, stitch, heat seal or other appropriate means.

In operation, the size ofloops 36 may be adjusted by appropriately positioningslides 16b and 16c relative tocord 15.Loops 36a and 36b are expanded and harness 10 fitted on the animal such thatfirst loop 36a is disposed around the animal's neck, whilesecond loop 36b is disposed around the animal's chest just behind the animal's forelegs. As such,first bridge portion 38a lies in the middle of the animal's back directly over the animal's shoulders, whilesecond bridge portion 38b lies on the animal's chest substantially between the forelegs. Once the harness is fitted on the animal's body, the harness may be further adjusted so as to establish a secure and comfortable fit. At this point, it should be apparent that the sizes ofloop portions 36b and 36c are directly dependent upon one another. That is,cord 15 passes throughcontrol slide 18 such that ifloop portion 36b is expanded, loop portion 36c will be contracted and vice versa. It should also be recognized that the tapered profiles ofslides 16 and 18 help to maintainloops 36a and 36b in a substantially open state when second edges 23 and 30, respectively, are disposed towardloops 36. Likewise, the orientation ofslides 16 and 18 is such that thefirst edges 22 and 27 are disposed towardbridge portions 38, which serves to maintaincord 15 in a substantially closed position. Withloops 36a and 36b in a substantially open state, and bridges 38a and 38b being maintained in a substantially closed position, the fitting ofharness 10 on the animal is facilitated. The closed positions ofbridges 38 and sleeves 39 or other fastening means cooperate to prevent the possibility that harness 10 will be improperly fitted. Sleeves 39 also serve to reduce snagging and tangling ofharness 10 while in use.

It may be desirable to provide akeeper slide 40 to be fitted around the third loop portion 36c so as to prevent the cord portions forming the loop 36c from sliding through the control slide under slack.Keeper slide 40 is preferably a length of vinyl tube or molded plastic piece having an inside diameter just large enough to snugly receive the adjacent cord portions.

In use, harness 10 is affixed to leash 11 by securingsnap 12 toleash attachment eyelet 19. It should thus be apparent that, as the animal strains against leash 11, loop portion 36c will expand as the cord is pulled throughcontrol slide 18, causingloop portion 36b to contract. The contracting ofloop portion 36b around the animal's chest causes a cinching or tightening action which is less comfortable to the animal. Accordingly, the animal acts in a manner to relieve the discomfort by ceasing to strain against leash 11. With the animal's comfort directly linked to the animal's behavior, a stimulus/response mechanism is established to discourage the undesirable pulling behavior. Not only does the harness discourage the unwanted behavior, but also does so in a manner which is much more comfortable to the animal than was previously known in the art.

The above-described invention thus accomplishes the objects of the present invention and otherwise improves the art.
